SYSTEM FOR ELECTRICALLY 6, 1911. serial No. 606,717.

To all whom t may concern:

VBe it known that I, IIERBER'L B. TAYLOR, a citizen of the UnitedY StatesV of America, residing at 148 Lancaster street, city of Al-L bany, in the countyzofAlbany andState of New York, have invented certain new and` useful Improvements inV Systems for Electrically Controlling and Operating Railway- Tramo-Controlling Devices, Yof-which the .following is a specification. Y

' My invention relates to lmprovements in systems for electricallycontrolling and op. erating railway trai'iic controlling devlcesi such as signals. Y

I am aware that railway signals have been electrically controlled. andoperated prior Veo , nal.

vwhich. are common tov all. electrically conto' this application, but believe that the sys-y tem employed for controliand operatlon as herein describedA and illustrated has notbefore been used. Neither is this specification intended to cover a particular type ofsignal, but covers a system of-control and operation adapt-able to anyv approved signal.

The objects of my improvements are To provide a more simple and positive means of electrical control.v To reduce in number the sizeof conductors Vrequired for the control and operation of the signal. To'provide a safe and lreliable means of'indicating that the signal has returned `toits `normal position after current is cut olf from such sig- To reduce to a minimum thefailures trolled andy operatedsignals. I attain these objects by the use of the system and various devices as herein described and illustrated llication, in which'z` Y y l l, Figure 1 represents' a complete unit forV bythe drawings which `accompany this specithe control and Operation of a` railway signal of the one arm semaphore type. Fig. 2 represents a controller with its ioperating lever, lock slide, safety andjindicationmagnet, the

vlever shown in Wh at-isknown'as the normal position. Figs. 3, 4and 5 represent the same controller and lever as in Fig'.r 2,-but in the different positions it will occupy when being Vmoved between the normal 'and reverseA position. Fig. Gshows the core 'and head of the safety magnet, v2O. f Fig. `7- shows the'core and head of the indicationmagnet,'21. Fig.

10 lrepresents a motor generator as an alter native meansV ofproducing the indication and caribe employed in placeof the apparatus shown in Fig. 9 if desired.`

rIhe unit of'control and operation as shownV in Fig. l consists only of such parts as are essential to this description and the claims which follow. 1, represents the bed plate of` CONTROLLINGAND OPERATING RAILWAYLERAFFIC- CONTROLLING Devious. y 1 f i Spiecication` of Letters Patent. f l, Patented N0V i original appnation sied August 1a, 1910, serial No. 576,821. HDivided 'and .this applicafioaalea rebruay an interlocking machine, 2, is the ,operating` r lever arrangedto swing on the spindle, '3,

which is suitably mounted on the hanger, 4. A slide bar, 5, is connected with the lever,`2,

above the spindle, 3, and arranged tomove across the bed plate, 1, when thelever, 2, is operated.

A bell crank, 6, is mountedto swing'on af .Y i

spindle, 7, which is alsosuitablyvmounted' n in a bracket, 8, (see Figs. 2, 3, 4 and 5,).

which is; attached to therframe of the inter- Y The' upper arm, 9, Vof the crank, 6, isconnectedto that vportion of the lever, 2, which extends VbelowV the spindle', 3, by la link, v10. The jlower arm, 11,V of` the crank, 6, is suitably conchine controller, 13, shown in Figs. 2,53, 4 and.' In the bedplate, 1, is formed'a short recess, 14, and a longerV recess, 15, the func-v tions of which 'will be-explained later. A'

.nected lwith'xthe wiper rod, 12, ofthe ma! locking dog, 16,-and: an indication dog, 17,

. y. are arrangedVv in theslide bar, 5, 4in such a( mannerl that they are free to be moved up` and down throughthe said slide bar, 5, into and out 'of lthel recesses, v14, land n 15,

respectively.- Directlyl over the center' O-f the recess, 14, and above and touching the slide,..5, is located'a rod, 18, and. above'the centerof the recess, l5, and in llike manner is located ya rod, 19. These rods, 18,and'f19.,

are suit-ably: secured ,in position by attach# fment vto'the frame of the Smachine., vf(not" *if* shown) on the bed pisa, 1, andi" aired-1y meer, the recess, 14, is secured a" safety or lock,"rv

. ohms resistance with comparatively fewA turns of a high resistance wire, such as Grer:`

magnet, 20 (see Figs. 2, 3,4 and 5), and tor theibed plate, 1, under the recess, 15 is similarlysecured an indication magnet, 21, (see Figs. 2, 3, 4 and 5). The coil of the sai''ety orlock magnet, 20, is composed of two windings, 22 and 23. The winding, 2 2, is of about one-tenth ohm resistance and is of large wire of comparatively few turns.

The winding, 23, is of labout 300 ohms Vre-Y sistance and is of small wire of comparatively many'turns. The coil, 24, of the indicationV magnet, 21, is wound to about 300 Vmansilver for instance. Through the coil of the safety magnet, 20, passes a core, 25,

having secured thereto a head, 26, withlugs :or projections, 27 and 27 (see Fig. 6) and through the coil ofthe indication magnet passes a core, 28, having 'attached thereto av head,-29.

The rod, 12, of the controller, 13, has mounted thereon and insulated therefrom the wipers, 36, and 31, and also theinsulat-ed tripping blocks, 32, 33 and 34. This rod, 12, is arranged to slide in the bearings, 35 and 36, (see Fig. 2.) On the controller panel, 13, are suitably mounted contacts, 37,

37, 38, 38', 39, 39', 40 and 40, also movable contact fingers, 41,-42,743 `and 44, and contacts41, 42, 43 and 44.

'An electrical source of energy, 45, preferably a storage battery, although a generator would answer as well, is connected with the positive and negative buses, 46 and 47, by wires, 48 and 49. Other buses form part ofv the controlling machine equipment, 50,

Y being a bus connected with each controllei for supplying current to the magnet, 55,

and the coil, 54, 51 and 52, being secondary` former, as shown in detail in Fig. 9. This secondary winding, 53, is arranged adjacent to a primary winding, 54,I which is lpart of the said induction coil. Another vcoil,v55.

called-'the contactor coil is adapted, as will be shown, to close a circuit from the battery, 45, through the primary winding, 54, of the induction coil.

The wiring and operation et the controlling and operating devices of the signal will now be described.

As already stated, the source of energy,

i 45, is connected between the buses, 46 and 47.

It the controlling lever, 2, be moved from the position shown in Figs. 1 and 2 to the position shown in Fig 3, the slide bar, 5,

edge, y17 a. (see Fig. v8) to engage the forward,sig

L wipers, 163 and 164, to move upward. As

fact that a'shunt. circuit-,f is made up from] will be moved forward over the bed plate,.1, L l the dogs, l16,-and 17, which aremovably arranged Vin the slide bar, 5, will'be forced downward by the rods, 18 and 19, the dog, 16, will enter theV recess, 14, and thedog, 17, will enter the recess, 15.` The dog,.17, is beveled on itstront edge and is adaptedto lift outofrthe recess, 15, if the slide bar, 5, is moved far enough yto permit the beveled end of the recess, 15. "The dog, 16, lioweveigf is not beveledfon its edge and therefore-will not lift out of the recess, 14, but must forced out by the action of the safety magnet, 20, as will be shown directly. As the 139 lever, 2, is .moved as described they controller rod, 12, of the cont-roller, 13, will be-moved upward until the various contacts operated;

in Fig. 3, the wiper, 30, will engage contacts,f$ 37 Vand 37 andthe wiper, 31 will engage co-ntacts, 39.and 39', the movable Contact i fingers, 41, 42, 43 and 44,`will not have been f moved. Current frointlie battery, 45, will now flow from the positive bus46, to ter-@ minal, 97, wire, 99,- to terminal, 100, ofV the.. safety magnet, 20; also' from-terminal, 97, fuse, 96, terminal, 95, wire 94,to terminaLi 98, of `safety. kinagnet,f20. Current from terminal, 100, passes through the higli sfistancelwinding,-23, to terminal, 101, 'and'Av current Ytrom terminal, 98, passes through the low resistance winding,l 22,.Ialsoltoter-y A. minal, 101." From this terminal current si. ,M passes over wire, 102, to contact, 38, thermal@ by jumper, 137, tocontact 37 ,wiper, 30, conklv tact 37 wire 141, to contact, `143, ofthe sig-.- nal operating mechanism, wiper, 163,0ontct, 157, wire, 158, field winding, V146, armature, 147, wire, 149, winding, 148, wire, 150, contact, 151, wiper, 164, contact, 145, wire 142,l Contact, 39, wiper, 31,'co-ntact,39, wire 106, tonegative bus, "47 `The current flowing in thisV circuit just? described will cause ithe armature, 147, to revolve `and bymeansof'- 'l suitable gearing levers`,etc., not shown, move the signal blade,v162, totheY position shown in the dotted lines. As4 the signal motor 147 becomes energized the coil, 148, whchl# is alsoY inthe moto-r circuit, will attractthe armature, 153, against the .stop'or'contactyf 155, for a purpose that will 'be described. Ast-he blade, 162, descends the lever, will beV depressed and lswing-on the pivot,M 161, causing the rod., 159, onfwhich are the the said rod moves upward the wiper, 164,-- will Vdisengage the contacts, 151 and 145,' opening the circuit at. this point. The motolv will, however, ycontinue torun `owing tofthe Contact, 151, wire, 152, armature, 153, com tact, 155, wire, 156,. tocontact, 145. As the A blade, 162, ieechesfthe positionshown inrths'l acta-,a unes, thefwiper, iea-aviiiftdisengig@ the contacts, 157 and 143,-andmove to the position show'ndottedi This will cut 0E all current,V from the motor randf'the coil, 148, permitting the armature, 153,- to "be pulled Yaway from the fcontact,:f155,:by thespring,

154,' thus opening--the'ciruit Jatithis point.

The only current now flowing from'fthebati, tery, 45, isf from lwire,14`1, toi contact, 143, l0

through Vslot coil, 165,ba'ck to wire,v 142. Thisslotcoil `fwill holdgthe signal in the position to which it has been moveduntil the controlling-lever, 2, is again moved to,

the. position shown in Fig. 1. As current passes over ,thel signal motor operating cir- ;cuit the safety magneti-will'lbecome ener'- Jgized and willliftitscore, 25,' with its head, 126, and force the'do'g, 16,` out of the slot, 14.

vThe core, however,will remain up until the signalmotor is out out by the wiper, 163. disengagin'g the contacts, 143 and 157.

While the core, 25 is up it will by means of the upwardlyprojecting lugs, 27 and 27 (see Fig. 6) prevent the'slide bar, 5,\being moved farther 'forward than the position in 3, as thedog, 16', which projects through the slide bar,4 5,*is arrested bythe lugs, 27

and 27. When, however, the core, 25,drops owing to the'dimin-ishingof the flow of current in the signal ino-tor circuit, the lever, 2,

yand slide bar, 5, can be moved farther forward or to the position shown in Fig. 4. As the lever, 2, isso moved the controller rod, 12, will move upward to the position shown and the tumbler blocks, 33 and 34, will shift the movable fingers, 41, 42,743 and 44, causiing them to pass over the contacts, 41', 42',

43' and 44, respectively; but as thecircuitsk controlled by th'ese contacts are non-operative during this p-art of the controller move-y ment no current will flow. rIfit is now desired to put the signal, 162, back to its original orstop position as shown in full lines,

' the lever, 2, is moved to the position shown in Fig. 5. This movement will move the controller rod, 12, downward, the wiper, 30, will disengage the contacts, 37 and 37 and en-y gage the contacts, 38 and 38', the wiper 31 will disen-gage the contacts, v39 and 39' and engage the contacts, 40 and 40. This movement will cut oft all current from tlre signal circuit, die-energizing the slot or hold-clear coil, 165, and permitting the signal toassume the stop positio'nzwhich will put contacts, 1,57 and 143, into engagement by wiper, 163, and contacts, 151 .and 145, into engagement lby'w-iper, 164, as shown inJFig. l. At the same time thetumbler blocks, 3 2 and 33, will operate the movable fingersas shown in Fig. 5, closing the indication circuit as follows:

It will be understood that the above described operations have been performed) in proper sequences and with due time intervals allowed for the physical accomplishment of the movements eXplainedy-for instance, should Ythe operator move thelever, 2, back to the position shown in Fig. l5 so rapidly as not to' give signal, 162, time to close contacts, 157 to 143, and 151 to 145 then the coil,53, would merely discharge a single impulse of very low amperage through the indication circuit. This current value would be limited by the resistanceV and inductanoe of coil, 165, sothat there Vwould be no release by means of coil, 24, of indication magnet, 21. In such ai case, the operator los the `circuit tomagnet, 55, and then return;A

more slowly to the indicating position of thel contacts, 157 to 143, and 151 to 145, the coil,
